The invention relates to the network technology field and especially relates to a method for establishing an interface group and an apparatus thereof. The method and the apparatus are used to solve a problem that interface group creation efficiency is low. The method comprises the following steps that a controller receives an interface group creation instruction, and the interface group creation instruction is used to instruct the controller to adopt a control protocol to make forwarding equipment create the interface group; and the controller sends an interface group creation message to the forwarding device, the interface group creation message is used for notifying the forwarding device to create the interface group including at least one interface, and the interface group creation message carries information of each interface in the interface group. Therefore, interface group creation efficiency can be increased so as to support various application scenes which need to use the interface group.
